# Google Authenticator Features

##### 
## Authentication type (3)

Software Token

Offers software tokens, which are applications installed on a mobile phone, wearable devices, or desktops and generate time-based one-time passcodes (TOTP) that a user can easily copy. Software tokens work both online and offline.

Mobile-Push

Offers mobile push authentication, which is a user-friendly method that does not require a user to copy a code, but rather accept or deny an authentication using a mobile application. Mobile push authentication only works when a user is connected to the internet.

Risk-Based Authentication

Analyzes users' IP addresses, devices, behaviors and identities to authenticate a user.
